Why Immaculate?

We encourage our students to think critically, to be driven, to be passionate, to find faith, and to work for the greater good. We ask our students to embrace high expectations, to become exceptional, and, ultimately to change the world...with the confidence that their Immaculate family will support them every step of the way!

We Are Family

Immaculate is a community with long standing traditions and a history stretching back to 1962. As our 7,000+ alumni will tell you, students at Immaculate create bonds that are rich and enduring. The vibrancy of our community can be felt in times of jubilant celebration, as well as in times when we look to one another for support. Students and families instantly feel a sense of belonging, and every student is treated with the same respect and dignity. When the Class of 2020 was asked what it means to be a Mustang, the overwhelming response was, "FAMILY!"

Rigorous Curriculum

Ignite your mind with an academic program that is exclusively college preparatory and features 45 honors level courses and 13 AP courses, plus many programs that will develop independent learning and critical thinking, reading, and writing skills. Academic programs such as International Relations, World Religions, Forensics, Graphics Arts, Project Lead the Way Engineering Program, CISCO IT Essentials Certification, Certified Nursing Assistant Program and Economics integrate individual student analysis and exploration with technology.

Community Service

Our students, whether they are Catholic or not, come to understand that they are part of something bigger than themselves. At Immaculate, we believe you can change the world at any age. Every act of kindness, compassion and service to others matters. Throughout the year, students are invited to grow in their personal relationship with God, learn about the Catholic faith, bond during class retreats, receive sacraments, worship together and put their faith into action. The Class of 2020 performed over 25,000 service hours over their four years! 


Integrated Technology

Immaculate was one of the first CT high schools to implement a school-wide initiative to integrate technology into the curriculum with all students using individual laptops in their courses. Thanks to cutting-edge technology and an already existing distance learning program with area middle schools in place, Immaculate quickly and seamlessly pivoted to virtual instruction during the pandemic. As Immaculate parents will tell you, "The school didn't miss a beat!"

School Spirit and Mustang Pride

The Immaculate experience doesn't end when the bell rings. Many of the greatest moments take place when our students come together in support of the school they love, demonstrating their Mustang Pride. Our "sixth man" is our Stable - the often noted respectful, but spirited student fan section having recently won the CIAC's Battle of the Fans competition. Immaculate's school spirit is second to none. Just wait until you experience your first Spirit Week at IHS!

Dedicated Faculty

Knowing how to connect with you and meeting you where you are, is at the heart of an Immaculate education. You will become the best version of yourself and we are dedicated to helping you reach your full potential. Our teachers can be spotted in the audience on your opening night and at Mohegan Sun cheering you on to a state championship. They take a vested interest in our student's academic, spiritual, social and emotional well-being. Why do our alumni return often to visit Immaculate? It's in large part due to relationships formed with our caring and dedicated faculty, staff and coaches. 

Athletic Excellence

As dedicated as we are to a rigorous, college-preparatory academic program, it is not just labs and homework here. Be a part of Immaculate's long-standing tradition of athletic excellence that builds champions on and off the field. Niche has ranked Immaculate an impressive #30 out of 298 schools in CT as "best for athletes." Inspired by outstanding coaches, our student-athletes have achieved countless conference and state titles with many going on to compete at the college level. "We believe that we will win" is not just the chant of our fans, it is the relentless pursuit of excellence that is in the heart of our athletes!

Fine Arts Program

Excellence takes on many forms and at Immaculate our commitment to the arts is no exception. Our students will tell you that no talent lies latent here. We embrace the arts and give our students countless opportunities to explore visual art, theatre and music. Faculty and staff help you discover and develop your talents, while our school culture gives you the confidence to try new things. The visual arts, band, choral and drama programs stay busy year round perfecting and showcasing their crafts and disciplines, receiving awards, accolades and recognition along the way!


Collaboration over competition. Whether you're a STEM enthusiast on the Brave Engineers team, a theatre buff who doubles as the starting baseball pitcher, or the editor of the school newspaper who loves volunteering with the elderly, one thing is constant: support at IHS. Everyone wants to see you succeed. It is a tangible, intentional and unique quality that sets us apart from other schools...and you feel it from your Mustang for a Day shadow visit as an 8th grader straight through to your future as a Mustang alumnus/a.

Extraordinary Outcomes

Development of the whole student leads to extraordinary outcomes and a quantifiable return on your investment. Spirituality, health and wellness, extracurriculars and personalized college counseling all come together during your 4 years. When you walk across the stage at graduation, you are a confident, faith-filled leader with the wisdom and character to succeed. Consistently achieving the highest SAT scores in the Diocese of Bridgeport, our graduates tell us time and time again that they were well prepared for the rigors of higher education. The Class of 2020 received $30M in college scholarships and awards!
